ENVELOPE OR PAPER BAG.

SPECIFICATION tanning part of Letters Patent No. 359,137, dated March 8,1887.

Application filed February 2, 1855. Serial No. 154,611. (No model.)Patented in England December 11, 188-1, No. 16,295.

To all whom it may concern:

Be it known that I, DAVID DALZIEL, of No. 6 Battlefield Crescent,Langside, in the county of Renfrew, Scotland,wholesale stationer, haveinvented Improvements in Envelopes or Paper Bags used for theTransmission of Samples of Grain or other Produce, of which thefollowing is a specification.

This invention is the subject-matter of English Patent No. 16,295, datedDecember 11, 1884, granted to me.

My invention is an improvement on that form of envelope or paper bag inwhich the mouth is provided with a lip at one side, the closing of themouth being accomplished by first folding in one-half of the mouth fromone corner to the side of the body having the lip, thus providingapocket across the body from side to side, next folding the mouth againin half on a line crossing the first told, and finally inserting the lipby turning or tucking it into the pocket. As heretofore constructed suchan envelope has been formed of a blank having a triangular pieceequivalent to one-fourth of the mouth removed, thus preventing thecomplete closure of the mouth, and has also been formed with atriangular lip which merely occupies one-half of the pocket, thusleaving an exposed edge which is liable to be caught and withdraw thelip,which renders the device insecure. Another defect exists in beingable to open the envelope by pushing on one side of the lip.

I have devised a construction of envelope in which the mouth is not cutaway, and the lip must be properly withdrawn before the en velope isopened.

My improvement consists in an envelope or paper bag in which the lipextends the whole length of the mouth, so that when folded the lipextends from side to side of the body and occupies the whole pocket, ashereinafter de scribed, and pointed out in the claims.

In order that my said invention may be properly understood and readilycarriedinto effect, I willnow describe the drawings hereunto an nexed.

Figure 1 represents the form of a piece of paper or other material fromwhich an envelope or bag is or may be made according to my presentinvention.

Figs. 2 and 3 represent the same in progressive stages toward thecompleted envelope or bag represented at Fig. 4. Figs. 5 and 6 representthe progressive stages toward closing the mouth of such envelope or bag;and- Fig. 7 represents such an envelope or bag when so closed, aportiononly of which envelope or bag is represented at the three last describedfigures.

In forming an envelope or bag according to my present invention a pieceof paper or other material of the form represented at Fig. 1 is stampedor cut out. This blank is formed with a rectangular back, 9, arectangular flap,

f, an extension, d, a bottom lip, c, and securing-lip i, the latterbeing the whole length of the mouth portion, and when the mouth isclosed to form the pocket, this lip extends across the body and occupiesthe whole width of the pocket. The material is doubled over at thedotted line a, in which form the said material is represented at Fig. 2.The material is then doubled over at the dot-ted line b, Fig. 1, andthen at the dotted line 0, in each of which stages the envelope or bagis represented, respectively, at Figs. 3 and 4. The parts (2 and e aresecured down by gum, paste, or other mucilage upon the part marked f,and the envelope or bag is complete.

For closing the month of an envelope formed in the manner hereinbeforedescribed, and shown at Fig. 4, the upper or open end is doubled over atthe dotted line 9, Fig. 4, in which condition the said envelope or bagis represented at Fig. 5. The said envelope or bag is then doubled overat the dotted line h, Fig. 5, into the portion shown at Fig. 6, whereinthe flap z, of a single thickness of material, is

turned with the point downward. This fiap i, whose outer angle ispreferably less than ninety degrees, is then turned in under the fourthicknesses of paper or other material already doubled down, ashereinbefore set forth. {In this condition the mouth of the said enveloithe annexed drawings.

Having now particularly described and as certained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. A blank for envelopes,which consists of arectangularback, 9, rectangular flap f, ex

' or bag is closed, as is represented at Fig. 7 of In testimony whereofI have signed my name this specification in the presence of two subtoscribing witnesses.
